l are also loose and slidable on the shaft `11. Be it known that I, SYvER LOE, a citizen of `inside of each of thel clutch members 17 is a the United States, residing at Minneapolis, l collar 19, ixed to the shaft 11 by a pin 20 or county of Hennepin, and State of Minnesota, l otherwise and having grooves 21 extending have invented 'certain new and useful Imalong its outer surface parallel with the provements in Alternating RotaryI Gearing, shaft, and each clutch member 18 carries a of which the following isa specification;

My invention relates to gearingl adapted to rotate' alternately in opposite directions. The principal object of the invention is to provide an easy-running operating mehc., adapted to automaticall reverse the revolutions of the drum or-ot er device While the rotations of the driving-shaft'continue in one direction. Q

My improvements are illustrated inthe acall times remaining within the groovesv .212 The purpose of this construction is to insure the )rompt and accurateintermeshingbf the teet of the clutchmembers when they are reci rocated to contact.

T e' shifting members 1,'8 are adapted to tiri with while they are .'slidable u on the riage 23 by yok'es 24, which loosely engage in annular grooves 25 in their hubs or bosses 2 6', the yokes being rigidly attached to the gure 1' is an en elevation of a washingcarriage is guided in its reoiprocator movements by ins orscrews 27, secure to'lugs 28 on the ase of the carriage and extendin through slots in a horizontal plate=29, whiclgl is attached to shelves 30 on the brackets 13.

The carriage 23 is reci rocated by means of a shifting-lever 31. his lever is carried by the threaded end portion 32 of the drumaxle 5, so that the rotations of the axle'will Fig. -2 is an enlarged central vertical section of a ortion of the machine and gearing on the line :c of Fig. 1. Fig. 3 is an enlarged front view of the operating'mechanism and adjacent parts shown in Fig; 1. Fig. 4 is a` top view of the same, some of thearts being shown in horizontal section; and igs. 5 to 10 show details of parts to be hereinafter fpar. tcularly described.

The upper arms 36 of the carriage 23, on which the yokes 24 are provided,'are suitably curved in outward and upward'direction to be frietionally engaged and moved by the alternate contact of antifriction-rollers 37, which are mounted on opposite sides of the hub 'or boss 38 of the leverl.A The Iarm 33 and the On the shaft y11 adjacent to the boxes 12 wheel l16, which is fast on the trunnion 5.

' the clutch-contacts. The lever is weighted vat its upper or free end by the enlargement -ment of the clutches, and its weight serves as lower of the two rollers 37, which seats in an carriage toward the right, and thereby sepay former shaft, in 4combination with a reciprolugs 34 and 35 are so arranged and positionedl that upon engagement of either 1lugwith the lever it will lift the lever and swing upward slightly past perpendicular position, whereupon the lever will gravitate to its seat at the opposite side, and thereby ell'ect a reversal of 39 to lcause it to gravitate quickly and effectively in causing the alternations of engagean aid in holding the clutches in place.l The annular recess 40 in the carriage 23 below the axis of the shaft 11 serves tolock the lever in placejuntil it is again lifted by the engagement of one of the lugs 34 or 35.

In. operation the crank-wheel. may be turned continuously in the sameA direction, while the gearing automatically and periodically changes the direction of the rotation of the axis ofthe drum. Ii upon starting to turnthe crank the shifting-lever is in the position shown by full lines in Fig. 3, continuance of .the operation will carry the lever inward on the threaded axle. 32 until it is en aged by the lug 34 on the arm 33, Whichwill ift the ever and carryit past the erpendicular and allow it to gravitate towar the opposite side. As the lever descends toward the ri ht theri hthand roller 37 will engage the inc ined su ace of the adjacent carriage-arm 36 and slide the rate the left-hand pair of clutch members and carry the' right-hand pair into operative contact. vThis change, of Aclutch-contact will change the effective pinion-drive from the lefthand pinion 14 to the right-hand pinion 15, and thus reverse the rotation of the gear-wheel 16, and thereby the movement of the axis 5. The movement in the direction last assumed will then continue until the lever has traveled inward on the axle far enough to bring the pin 35 on the gear 16 to contact with the lever, whereupon the latter Will be lifted upward past vertical position and permitted to gravitate to the left to the assumed starting position andthe operative devices will again be in their first positions'.
